Intel Core HP Pavilion G4 Notebook Review

Posted at February 3, 2012

Pavilion G4, HP Home Series notebook, listed have been for some time, initially listed G4 using the first generation i-series processor and discrete graphics configurations. With the popularity of the SNB platform and Intel Core Graphics for the majority of notebook users gradually recognized by G4, are beginning to use second-generation i-series processors as a mainstream configuration, then the next-generation Compaq Presario CQ32 battery platform, G4 series of notebook performance actually had What progress, Intel’s Core graphics compared with the low-end discrete graphics in the past in what characteristics? Let the author for you to uncover its secrets.

First, the appearance of the overall impression

As part of the overall evaluation, or need to simply look G4 appearance characteristics. Compared with the initial public offering, G4, in appearance and no new changes, if not personally check the boot, I am afraid no one would think that this is a new generation of SNB platform products.

The G4 series as a whole, stable, generous-based, machine metal gray tone, borders, B shell and bottom shell part is black, dignified but not rigid. The superstructure of the front Compaq Presario CQ42 battery upper right corner of the big HP metal signs. The shell is made of special treatment, has a metallic luster, but easily contaminated with fingerprints.

G4 display with HP BrightView bright screen 14.0-inch high-definition LED display, camera, digital camera for the integration of the MIC.

It is particularly worth mentioning is that the G4, ingenuity in keyboard design, the commonly used in the F1-F12 key functional design has become the shortcut keys for various functions, such as brightness, display switching, volume adjustment, Wireless LAN switch. Need F1-F12, you need to press the FN key to cooperation. Just get started, felt somewhat accustomed to, but used for some time, you can feel the design is hand to facilitate a lot.
Audio interface design, and adhere to the separation of design of the headphone output and microphone input, compared to the part of the notebook Compaq Presario CQ56 battery combo design greatly facilitates end-user.

Taking into account the convenience of connecting flat-panel TV, G4, still retained the HDMI interface, flat-panel TVs in the home can directly access the laptop computers, to fully enjoy the shock effect of the output of the big screen.

CD-ROM drive is equipped with a DVD burner that supports Lightscribe technology can bring a lot of convenience for the user. Burn content at the same time, the user can also add some personal characteristics of the CD cover.

Aspects of the speaker, G4, the Altec Lansing speaker system, and supports SRS audio, the overall effect of a lot better than the other brands of notebook speakers.

G4 touchpad supports multi-touch, and designed a concave shell and an orange light in the upper left corner of the touchpad with your finger gently double-click the pits, the indicator light, this time the Compaq Presario CQ62 battery touchpad has been disabled. again double-click the pits, light is off, the touchpad on the restoration of normal, and can be considered a characteristic of the design.

In addition, three USB ports, a wired network interface, multi-card reader, wireless card support 802.11BGN fully meet all the needs of the user.

Second, the main configuration

This one the latest SNB platform using Intel’s Core Graphics HD3000, the overall processing and graphics performance than the integrated graphics used in the past has made significant progress, G4, some products directly using this design, I get specific model G4-1018TU, the i5-2410M processor, the processor HP Pavilion G7 battery 2 core, 4 thread standard clocked at 2.30Ghz, Core frequency up to 2.9Ghz, the L3 cache is 3MB, HD3000 Core Graphics, 2GB DDR3 memory, hard disk configuration using the 5400 produced by Toshiba 640GB hard drive.

Third, the performance test

(A) 3Dmark 06

As the aircraft display support resolution up to 1366X768, does not support the requirements of the minimum 1280X1024 3Dmark Vantage, do not take the external display only 3DMARK 06 test, the test for the CPU, the final score of 3025.

After an external display and the resolution set to 1280X1024, 3Dmark Vantage, can be up and running, only the CPU part of the test, the final score of 8288.

(B) PCMark Vantage

From the perspective of the overall results of the PCMark Vantage Software 5485, HP comes standard with a new generation of i5-2410 processor, the achievements made by the HD3000 Core graphics card and 2GB DDR3-1333 memory is not high, but for the average user to meet general family entertainment needs is no problem. In this test, the next-generation CPU core architecture and integrated on the same chip HD3000 Core Graphics has played a key role, can replace the low-end discrete graphics, while maintaining low power consumption and meet the customer’s mainstream applications. needs.

This is a test-Apple iTunes software, the high bit rate MP3 songs HP Pavilion G4-1000 battery converted to iPod AAC format, a total of 10 MP3 songs (a total of 131MB), take a manual timing. Another comparison test laptop is a Dell E6410, the main configuration: i7-740QM processor 4GBDDR3 (1066) memory, 500GB (7K500), NVS410M graphics card (512M memory).

The final outcome of the test as follows: E6410 (i7-740QM) with a time of 2 minutes 31 seconds 85 HP G4, (i5-2410M) with only 1 minute 32 seconds 90. In this test, a new generation of CPU-leading rate reached 39%. Core Graphics on this result, we still feel a bit surprised to joining Intel Advanced Vector Extensions instruction set (AVX) to enhance overall system performance is so obvious. With the help of a new generation of Core Graphics, non-professional audio and video editing users may also need to spend expensive hardware can fully enjoy the fun of audio and video editing.

(D) video conversion test

Software Movavi Video Convertor 9.2.2, the raw material for the MOV format, with a resolution of 1920X1080, long piece of 1 minute 9 seconds, the size is 380 MB, the conversion of the target format is the mpeg4 resolution of 1280X720. In this test, the E6410 to complete conversion tasks with 2 minutes 50 seconds, G4, with 2 minutes 10 seconds, the leading margin of 23.5%.

Our impression, in this video converter application, with discrete graphics results are often ahead of some. But tests showed that, using the Intel Core Graphics system has been completely overturned our traditional image of HP Pavilion G6 battery reason, we believe that is the Intel Core Graphics built-in high-speed video synchronization technology plays a key role in this built-in hardware acceleration technology greatly improves the performance of video conversion and editing, and finally to the G4 to obtain good results leading to 23.5%.

(E) game test

The use of Street Fighter comes with Benchmark test, using the default settings, turn off anti-aliasing, the final score was 7073, the average frame rate is 25.97 can only be regarded as basic smooth.

(F) temperature test

Room within the room temperature of 25 degrees, and G4 for general applications, such as Internet access, document handling, temperature control of the whole keyboard, palm rest and the temperature did not exceed 31 degrees Celsius, the air vents at the temperature, but also 33.2 degrees.

3Dmark06 software) test (continuous operation under full power HP Pavilion dm4t battery conditions, the maximum temperature of the keyboard area of 35.6 degrees, the palm rest is up to 34.5 degrees, still maintained a better comfort, the air vents at the temperature reached 49.2 degrees. This test results in the previous discrete graphics on the machine is rare, it is because of strong performance, power control and excellent Intel Core Graphics, which makes the overall system power consumption and temperature control a more reasonable and comfortable within.

Fourth, the test summary

After the above tests can be seen, HP Pavilion G4 battery, thanks to a new generation of SNB platform, the whole performance than the previous generation platform with significant progress, whether it is audio and video converter or general office applications are significantly higher than the previous generation. the CPU, but also worth mentioning that within the CPU integrated HD3000 Core Graphics can replace the low-end discrete graphics cards to run in general 3D also reached a degree of smooth, fully meet the needs of non-professional gamer. Machine power and temperature control is also done quite well, even in the case of full power, remains a good comfort.

Battery Tips

Toshiba R800-or ever dreamed of R?

Posted at February 2, 2012

First, the shape features

Although the Satellite R800 and R700 is not the same machine, but the shape and weight point of view, it inherited the characteristics of the R Series is light, thin. Thickest machine only 2.78CM the same type of machine is rarely seen in this thickness. As a 14-inch display, built-in optical drive and discrete graphics machines, weight control in 2KG (measured 2.037KG the) around truly become a collection of slim form factor and high performance in a leader.

In addition to these features, the difference between TOSHIBA Satellite 1400 battery it and the R700 is the technology and materials on the superstructure and the bottom shell of the R700 alloy material made of, disassemble later, we found that, due to the relationship between positioning and price. R800 roof and the bottom shell has been changed to a plastic material, the reason why on the cover of corrugated craft, in addition to the appearance of factors appropriate to strengthen the strength of the plastic material should also be one of the reasons.

Shaft design, the R800 is still sinking design, thus making the maximum open angle of the display 140 degrees, the following picture is the picture in the maximum open angle.
At the top of the touch pad, we also found a touchpad switch, use this switch, you can easily disable or enable the touchpad, this feature is often a lot of text input user can effectively prevent the mouse scurry and misuse operation.

Second, the hardware specifications and interface design

The R800 series is equipped with HM65 chipset, i3-2310M (2.1G 3MB L3 cache), the use of AMD Radeon HD6450M’s HD graphics card, memory up to 1G.

R800 is the color of the 14-inch LED HD 16:9 aspect ratio Hyun, a resolution of TOSHIBA Satellite 1555 battery 1366X768, and view the actual results, whether it is to play HD movies or 3D games, screen brightness, the contrast is very good, completely meet the needs of personal entertainment
Located around the shaft near the two-channel speaker, a strong presence in the play HD movies, only with a single speaker, at best, be regarded as a sound machine, stronger than many.

In interface design, in addition to VGA, RJ45, USB 2.0, headphone, microphone and multi-card reader, the R800 introduces a USB3.0 interface, and HDMI, USB3.0 interface, greatly enhanced the introduction file copy speed, especially in the case of hundreds of hundreds of GB of HD movie files, more meaningful. I tested top speed of Mach USB3.0 32GB U disk, the average TOSHIBA Satellite 1800 battery read and write speed of 70MB / s, 1GB of files in just ten seconds of time you can copy finished.

Third, the internal universe

This test, we are not limited to appearance and performance testing, a part of the dismantling of the machine. On the whole, the difficulty of the dismantling of the R800, or maintainability, compared to the ThinkPad machines, there are still some distance, such as the use of screws is more complicated and vary in length, only the memory cover and hard cover on the use of the length of different three kinds of screws, but due to the hard drive cover to the side of the pressure in the bottom of the memory cover, leading to want to change the hard drive had to first remove the memory cover.

Specific dismantling behind labeled KB of a screw removed, pull up and then a small strip TOSHIBA Satellite 220 battery above the keyboard, you can see the keyboard of a small clamp, push back the clamp can be loosened. then the keyboard upward, you can remove the keyboard.

Remove the keyboard, the next step is to remove the bottom cover. Remove all the screws in the bottom shell, bottom shell can be taken down.

R800 and did not take the traditional way to install the cooling fan, but put it in the bottom of the radiator for cooling duct formed in the rear cover cover. We know that the machine using a separate graphics card, relatively speaking, the heat is relatively large, fan size will be larger, thicker. This also means that lead to such machines can not do very thin, while Toshiba’s designers have cleverly taken to separate the design, which reduces the thickness of the entire heat sink, this makes the R800 in the machine thickness and The performance achieved a good balance point. Some readers may ask, relying on such a duct, the cooling TOSHIBA SATELLITE 2435 battery effect of line? This is exactly what we are worried about the problem. On this issue, we give below a temperature test to unlock the hearts of mystery.

Needless to say, this is the heart of part of the CPU of the machine, the specific model of i3-2310M. Do not know since when Intel canceled directly marked on the CPU model and parameters. Only from the chip above, we can not see that it is what type of CPU, only to see from the machine information.

Fourth, the performance test

(A) audio and video conversion
Audio conversion, we still use 13 high-bit rate MP3 songs, a total of 131MB, converted to AAC format using iTunes software R800 use when 2 minutes and 4 seconds 15, the comparison test is the DELL E6410 (i7-740QM 4GDDR3, NVS410M ), the E6410 with 2 minutes 31 seconds 85, R800-leading margin of 18.2%.

Video conversion, the material TOSHIBA Portege R700 battery is a 380MB mov HD movie resolution is 1920X1080 Duration 1 minute 9 seconds, convert 1280X720 mpeg4 format. The use of the software Movavi Video Convertor 9.2.2. E6410 complete conversion tasks with 2 minutes 50 seconds, the R800 with 3 minutes 4 seconds. For this result, we also feel very strange, after all, i3-2310M frequency a lot higher than the i7-740QM. To prevent errors, we conducted a total of three tests, the results of error in less than three seconds.

(B) 3D Mark 06
The resolution of the R800 can not meet the requirements of the 3D Mark Vantage 3D Mark 06 test, set the resolution to 1366X768, turn off anti-aliasing, the composite score of 4059, fully meet the needs of 3D gaming in general.

(C) PC Mark Vantage,Final score of 4863 points, the score is not high, for business applications, without any problem, from our actual experience, either online, or working with pictures, high-definition video, the machine response very quickly, did There is no feeling of dragging its feet.

Fifth,Temperature and battery life

(A) Temperature test.TOSHIBA Portege R835 battery Is set to 25 degrees Celsius in air-conditioned office, the full load test, the R800′s keyboard area is a maximum of 35.5 degrees, the outlet temperature was 49.2 degrees, it should be said that this temperature is quite high. At room temperature 30 degrees, no air-conditioned environment, comfort will have some impact. In the process of testing, we obviously can feel the outlet of the hot air continues to blow out, and install the fan on the radiator of the machine compared to the amount of wind or a lot, which to some extent on affect the cooling of the machine, but Fortunately, the temperature is still in the acceptable range.

This is the full load test results. The average user in the Internet when the temperature in the office without any problems, just carrying out large-scale 3D games or audio and video converter, you may feel slightly unwell.

(B) of battery life
The R800 is equipped with 6-cell battery voltage is 10.8V, capacity 5800mah TOSHIBA Portege R830 battery Imtec Battery Mark software testing, and full load case, the life time is 2 hours and 19 minutes. The general office application time of not less than five hours.

Six, test Overall

From the test we can see that the R800 as the most important models of Toshiba business with the machine, both are very good in performance and portability on a machine to keep the light on the basis of the simple pursuit of frivolous ultimate PORTEGE series machines has been greatly improved in performance, fully meet the various needs of the user.

Excellent Choice For Commercial Lenovo ThinkPad T520 Review

Posted at February 2, 2012

When you see the Lenovo ThinkPad T520 notebook when there may be many people and I have the same feeling that it has a rigid design style, always brings a warm feeling, but some people would be so old-fashioned design will produce fatigue. In any case, this impeccable classic design is still a lot of the reasons customers choose it, because the ThinkPad T Series notebook is a pure business model for, without too much modification can change the user conquer the pursuit of classical .

Calm, classic style black business

Lenovo ThinkPad family as the most talked about products of the main business notebook, 15.6-inch T520 in the overall appearance of the design still maintains the characteristics of previous Lenovo ThinkPad E40 battery generation products, pure black body dignified low-key, steady, introverted, in line with business style. At the same time cover the surface with a high-touch spray fine grinding process, in addition, commendable magnesium roll cage built to provide users with the most efficient data protection.

Lenovo ThinkPad T520 has a wide touch Korea off the keyboard feel is perfect, but still retains the keyboard pointing stick in the center of the design, which also takes care of the old user’s habits. Interfaces in addition to the common D-Sub port, but also joined the DisplayPort high definition video output port. At the same time care location in the right palm also for business to provide high security fingerprint reader, and the bottom of the fuselage slot docking station notebook interface, greatly expanded the type and quantity.

Through the above brief introduction, we have been on the overall appearance of this Lenovo ThinkPad T520 have made a preliminary understanding, and a more detailed Lenovo ThinkPad E50 battery description, please see the next chapter.

Classic “black” style reproduction

Lenovo ThinkPad T520 in the design aspects of other T series models with the same pure black appearance of calm in line with requirements of business notebooks, low-grade sense of coexistence is restrained and T series much like the reasons for business users, the overall design of simple models able, prominent business qualities, and continued the classic design of ThinkPad T Series.

T series cap on the matte painting process not only has a good touch, but also to the whole look is fairly upscale feel, embedded ThinkPad roll cage is a unique high-end business notebook protection technology, with focus on the body around the main components within the framework of magnesium alloy, when the notebook bump or fall accident case, the roll cage to provide users with hard disk protection, as well as critical system component parts notebook internal security.

ThinkPad T520 does not use a sink-type screen shaft design, so the screen is not less than the maximum open angle 180 °, this design is necessary for business users, can be adjusted according to actual situation of freedom of the screen angle, in the business application provides the user with convenience and choice.

Lenovo ThinkPad T520 with a 15.6-inch LED backlit matte display, the process of making use of renewable materials and mercury-free materials, has EPEAT Gold certification and Energy Star 5.0 certification, the maximum screen resolution of 1366 × 768 pixels, and the generation ThinkPad T510 compared to Lenovo ThinkPad L420 battery adjustment for 16:9 screen ratio, which has been used with a 16:10 screen ratio in terms of business will no doubt feel a little meet, but as more and more rich in high-definition video format, 16:9 aspect ratio more in line with current usage requirements. In addition, the matte screen is designed for users who frequently go out of business very close, in strong light conditions can also be used to ensure that users can clearly see the display.

Lenovo ThinkPad T520 body interface layout compared with the previous generation, there are some small changes, let’s take a look at the distribution of the fuselage right side of the interface. This includes Express Card slot, multi-card reader, headphone / microphone jack mix, DVD burner, RJ-45 Ethernet port and security slot.

On the left side, left to right, respectively, with high-definition output interface DisplayPort, D-Sub video output port, two USB 2.0 ports, an eSATA / USB 2.0 interface and the wireless switch. Overall, the layout of the fuselage both sides of the interface, though more compact, but at the same time for ease of use is not too great.

As the laptop did not use home screen as the sunken shaft design, the T520 back in the fuselage there is enough space to provide users with a number of interfaces, including support this charge off the USB 2.0 interface, a, 1 RJ-13 interfaces and power jack. The back of the USB interface configuration is a good idea, so that allows users to use a wired mouse, the cable will not feel complexity.

Meticulously detailed work

Understanding of the T520′s overall design features, we look at some of the details of its design part. As a 15-inch large-size notebook computer, T520 thickest part of the IBM ThinkPad T22 battery body has reached a 4cm, but the body design and smooth lines, a good grasp of the body, it does not look bloated.

T520 top part of the addition to the printed “ThinkPad” logo, but still left with a metallic mosaic of “Lenovo” logo, and a black stroke to distinguish it with the cover, looks great texture, as a whole design adds a lot of energy.

In the ThinkPad T520′s screen has a built above the common user network camera, video conferencing business users to use to make web conferencing communication purposes, while depression in the camera position, still night designed to help users type of auxiliary lights, and directly through the keyboard “FN + PageUP” key combination can realize the function.

When the ThinkPad notebook for evaluation, there is always much appreciated for its screen axis, T520 is no exception. The model uses a two-stage processes symmetrical screen hinge, proud of this design principle, the screen can be freely open for more than 180 degrees. In addition, the ThinkPad-specific integration into the production process hinges, you can ensure that the screen at any angle with good IBM ThinkPad X60 battery damping strength, and does not adjust the angle, the screen goes back and forth situation.

Attention to detail is the key to success, the design of the laptop is particularly the case, although the details of the design does not necessarily recognized by the user, not necessarily with any practical value, but able to maintain a sense of the overall grade. This is, from T520′s Express Card slot on the baffle can be seen, although the honeycomb design has no practical use, but you can feel the careful design.

High-touch comfort keyboard

Opened the screen lid, ThinkPad keyboard layout on the show in front of, I believe that friends are familiar with laptops know, ThinkPad notebooks can highlight their best features is the host of the keyboard surface should be designed, this ThinkPad T520 is no exception , you can clearly see the keyboard above the “ThinkVantage” keys, keyboard, TrackPoint central location of the red and blue background of the “Enter” Enter, the design of ThinkPad T Series notebooks are the signs.

Power button design seem unimportant, but often have a potential impact on user experience, the market power of some key design notebook products slender, narrow, and some even into the body more, these small details seem like much, But what is by then, will make people feel uncomfortable. The most appropriate power IBM ThinkPad X60S battery button design, we should pay attention to the area of Cap, but to pay attention embedded in the depth of the fuselage, Cap, small size, embedded in the body too, are not comfortable, and T520′s power button design is very reasonable , and finger belly area is quite, and with the flat surface of the body, so that when a very comfortable touch to enhance the user experience, naturally, can be subject to user acceptance.

The upper left corner is the distribution of the keyboard function keys areas here, including two volume control keys, the key to open the microphone and ThinkVantage shortcut keys, keycaps designed, user-friendly.

High-touch keyboard and the “Little Red Riding Hood,” pointing stick is a traditional ThinkPad notebooks feature much ThinkPad notebook users also recognized local, traditional, trapezoidal keycap tactile, key-way control in the very place, so the overall hit feel very comfortable. Red pointing stick set in the heart of the keyboard, a touch of black in the embellishment. Control the mouse pointer using the IBM ThinkPad Z60t battery pointing stick is very sensitive, habits, and in many cases can replace the mouse.

Left andright sides of the body surface of the speaker C

Matte wrist rest design

Fingerprint reader ThinkPad T Series is the product of the standard equipment ages, is very important for the business user, you can effectively protect systems, data security, to avoid important information being stolen is an important barrier.

Equipped with a fingerprint reader to enhance system security

Comfortable touchpad design

Lenovo ThinkPad T520 touchpad surface using a fine, textured bump lines, slide the pointer finger when the target position are very accurate time, even a slight point the finger sweat will not be greatly affected, while the use of multi-touch touchpad technology, viewing photos or browsing the web, the user simply by two fingers on the touchpad can be done zooming, scrolling, and rotation operations, which IBM THINKPAD 380 battery make up the pointing stick in these operational deficiencies.

Lenovo ThinkPad T520 with a 15.6-inch LED-backlit display, body length 372.8mm, width 245.1mm, thickness of 31.8mm-35.6mm, weight is about 2.6kg (official information), In addition, the laptop does not boot features interface also includes USB charging port and the bottom of the fuselage docking slot, to improve the practical operation of the user ease of use.

In order to give business users with richer and easy mobile computing experience, ThinkPad T520 notebook computer is equipped with essential business functions in many companies. Such as the Internet for the convenience of business people to the meeting, ThinkPad T520 for video and voice features are optimized for users of VOIP experience better; In addition, there are many designs for business security, such as super-user password, APS hard drive protection, emergency and recovery systems and other functions, the protection of all aspects of business users to maximize system security.

In addition to these commercial properties in addition, Lenovo ThinkPad T510 battery is also equipped with NVIDIA NVS 4200M professional graphics card, let’s take a look at this card and the focus on ordinary GeForce graphics What are the different aspects.

Familiar with the fine TV series GeForce graphics cards in different classes, NVS is for the professional graphics card business users, so the game can not use conventional tests to measure its value, but also not to treat GeForce attitude towards NVS. Since it is a professional business graphics cards, then it was required for business applications designed for targeted, such as up to four monitors can be easily achieved with the same split-screen display; such as its support for the professional business software and Web browsing acceleration etc., can help improve the efficiency of professional users for its convenience, these are the common GeForce graphics cards are difficult to achieve.

Business office assistants

Lenovo ThinkPad T520 T-series as a new generation of the main models, in appearance remained largely on the previous generation of the classic design style, body in size, thickness and weight changes are subtle, while the interface layout and some small details also slightly changed, but the machine still adhering to the ThinkPad family of outstanding quality and rigorous work of the overall structure.

15.6 inches in the drawing for the big screen is undoubtedly the work of IBM ThinkPad R50 battery friends is very appropriate, but 1366 × 768 pixel screen resolution of slightly less, from this evaluation, we can see, T520 still maintain a professional Business notebook features office tool, in many respects the particularity of business applications for the design, so for business users, has a decent user experience.

In the hardware configuration, we get the evaluation of this model uses a more mainstream hardware platforms, the Intel Core i5 2410M processor, 2GB DDR3 memory and 500GB hard drives are the most mainstream of the current configuration, but also be able to best meet the business needs of the user’s configuration, the overall performance is more balanced. In addition, graphics cards, using the NVS 4200M professional graphics cards, graphics cards with Intel Core dual-graphics, effectively guaranteed life. If you are using Windows 7 operating system, then I recommend upgrading the memory or 4GB, it will be more fluid experience.

Overall, in the field of high-end business notebook, ThinkPad T series of quality and user acceptance are at the top position, the series model is the use of laptop computers for each user who dream office products, T520 Although there was no appearance qualitative change, but still do not disgrace the high-end ThinkPad T series character.

In the hardware configuration, the Lenovo ThinkPad T420 battery is equipped with 32nm process technology Intel Core i5 2410M dual nuclear power plant thread processor, equipped with Intel QM67 chipset, configured together high-capacity 500GB 7200RPM hard drive, the memory capacity of 2GB, 2GB DDR3 by the one -1333MHz memory speed to achieve, in addition, the machine factory pre-loaded with Genuine Windows 7 operating system. In the video, the model equipped with NVIDIA NVS 4200M professional graphics card, its features can help business users achieve better graphics, multi-screen output, and application experience.

Before the start of the performance test, we first AIDA 64 of CPUID tool to see Fengyun Intel Core i5 2410M dual-core processor’s basic information, which is based on 32nm process technology, the core code-named Sandy Bridge, the initial frequency of 2.3GHz, technology to accelerate the use of Turbo 2.0, the frequency can be upgraded to 2.9GHz, shared L3 cache is 3MB, the overall TDP of 35W, supports Hyper-Threading technology with the latest AVX instruction set.

The card has 48 stream processors, memory capacity of 1GB, Memory type GDDR3, memory interface is 64bit, frequency of 810MHz, the GeForce common with our entertainment, games, graphics different, NVS 4200M graphics card is not good at running 3D games, so we do not test their game performance, only 3DMark Vantage score by an understanding of its performance, and ultimately, GPU part of the E mode, got a score of 10275.

Lenovo ThinkPad T520 battery together with a 500GB 7200RPM hard drive, HD Tune we tested its performance. Screenshot from the test results, we see that the average transfer rate of this drive 77.5MB / s, the maximum transfer rate of 99.8MB / s, while the minimum transfer rate of 47.2MB / s, plus 17.6 ms access time obviously stronger than the ordinary number of 5400RPM hard drive performance.

Finally, the overall performance of this product was tested using the software for the PCMark Vantage, which is a common comprehensive performance assessment notebook software by simulating the user a variety of practical applications for everyday use in all aspects of notebook gives the corresponding the assessment results.

Select A New Experience Of ThinkPad E420s

Posted at January 31, 2012

Lenovo ThinkPad E420s are the elite version of the Edge series of high-end models, it is in the ThinkPad tradition of models based on the number of added elements of fashion, created a new generation of standards for high-end business machines, simple appearance, exquisite design, strong performance and configuration, slim, lightweight body, undoubtedly those of us used to the traditional users of the Lenovo 3000 C200 battery machine to its ThinkPad series has a new look and desire.

Although previously we have from many sources to understand the information about it, but get real machine later, still a little surprised, it changes actually so great: smooth corners, shiny chrome frame, the integration of the metal bottom shell, like a mirror of the LCD glass, this is the familiar ThinkPad it? In addition to the red dot that is still alive and the body much of the ThinkPad Lenovo 3000 N200 battery logo, ThinkPad I did not find more then the other elements.

A change in appearance

Speaking from the first color, take E420s and other than the traditional ThinkPad machines, first discovered it is no longer the kind of color the color of black, similar to gray-black.
Information from the manufacturer to see is dark green, but I do not see how it is dark green, so that other colleagues read, no one can see it is dark green. Perhaps only in the sunlight, in order to show that touch of mystery it.

In hand machinery and control the opening and closing the screen, we can feel the rigidity of the body well, even from off the edge of the screen, its deformation is small, not like some brands of household machines in his hand always felt creak to ring, worrying will not fall apart. It Lenovo 3000 V200 battery is used in alloy cover with glass fiber, the entire bottom shell is made of metal, the intensity is high, pushing down the outlet without the slightest distortion.
The whole body is a kind of coating used, similar to the previous kind of skin texture coating 600E, but not exclusively, that feeling.

Another change is the ThinkPad logo itself, the letter i above points into a red, and light up automatically when turned on, of course, this change can not be regarded as new, because before the Edge series E40 model has been the case.

Bottom of the change is relatively large, E420s using the integration of the bottom shell, hard drives, like the original, can be extracted directly after the replacement. However, battery, memory is hidden in a body inside, purpose of doing so is self-evident, is to make the elite Lenovo Thinkpad X60 Tablet battery version of the ThinkPad Edge slimmer.

Review the history of ThinkPad models, we can easily find, ThinkPad generally accepted reason for the majority of users, it is important because they regard the user ease of use on the top, of course, including the maintenance convenient.

E420s out of the LCD screen using a high hardness of the glass without borders, making the B-side like a mirror. Nevertheless, it benefited from the superb anti-glare technology, not only effectively eliminate the phenomenon of reflection, leaving display unexpected.
Change the keyboard is relatively large, and before the Edge series machines, X120E, like, E420s also used a six-row floating island-style keyboard, in the row of buttons on the Lenovo Thinkpad X60 Tablet PC battery arrangements, such as volume, brightness, display switching, wireless switches, etc. Some commonly used function keys.

And we used the keyboard is not the same, F1-F12 keys and function keys for the switching, direct press these buttons, use the function keys F1-F12 keys to use, you must use the Fn key combination red corresponding button. Relative to the F1-F12, the majority of users when using the function keys a little more, this change added more fit the user’s actual situation.

The use of chrome metal frame so that E420s have become more modern and stylish feel.
Second, the machine configuration

Dedicated network to get this E420s (4401-32C) using the CPU is i5-2410M, 4GBDDR3 memory, and AMD ® Radeon ™ HD 6630M graphics card (2GB memory), is particularly worth mentioning is the E420s with a dual-drive configuration way, in addition to the common high-performance 320GB 7200 rpm hard drive, but also the additional use of a piece of Intel mSATA interface, 80GB SSD, because SSD read and write faster than mechanical drives, use it as the operating system disk, you can greatly improve the Lenovo 3000 F40 battery for startup, shutdown, and efficient access to large applications, this configuration, SSD prices still remain high in the current case, both the performance and capacity of the dual needs.

In addition to high-performance graphics card Radeon HD6630M addition, E420s also uses the Intel Core Graphics, both to meet the general application requirements, but also can greatly reduce the power consumption of the machine, thus extending the life of the machine. Two kinds of cards can be switched at any time, users can for each specific program, a separate set of high performance (discrete graphics) or power (Intel Core Graphics) mode, but this set is way better than the direct use of a general feeling key conversion convenient and practical.
Third, the external interface

From the configuration table, we can see, E420s provides some common interfaces such as USB2.0, RJ45, VGA, HDMI, eSATA, one headset jack, 4 in 1 card reader, etc., can be found attached to the arrangement of the interface Fig.

The first one on the right side Lenovo 3000 F50 battery USB port is a yellow, in the case of external power supply, USB devices can be powered directly. With the increase in personal electronic devices, daily travel time bag with three or four cases of electronic devices has been very common, and sometimes what the device will inevitably encounter a sudden no power, and this time if you have a bag E420s, it can be a good alleviate this predicament.

E420s using the HDMI interface is a very commendable place, connecting high-definition Lenovo E420s battery flat-panel TV on the convenience, HDMI to be significantly better than the DP interface, the vast majority are used in flat-panel TV HDMI interface, HDMI is inherently for the audio and video designed with the transmission, the connection is also very convenient. Fourth, the performance test

E420s overall configuration is relatively high for its performance, we also have many expectations, let’s specifically look at its true performance.

(A) CPU performance. We still use the SUPER PI software testing. E420s of one million and 200 million bits, respectively with 14.04 seconds and 32.167 seconds. From the results comparison chart we can see, the second generation of i5-2410M processor performance over the first generation of i7-740QM.

(B) hard drive performance. E420s Lenovo Enhanced Experence2.0 technology is the use of models, combined with solid-state hard drive, startup and shutdown speed can be achieved. This E420s are installing 64-bit version of Windows 7 Professional operating system to load during startup and a power indicator. Press the power button from the start time to start is completed, only 25 seconds. Shutdown Lenovo ThinkPad Edge E220 battery speed is amazing, only a short 7 seconds. This switch speed have left a deep impression, which apart from its high-performance SSD outside, Enhanced Experence 2.0 also play an important role.

Here we use HD Tune Pro software for this mSATA interface SSD screenshot when tested. From the figure we see that it reached a maximum read speed of 203.3MB / s, average speed of up to 177.6MB / s, access time of only 0.1ms, no wonder the speed switch will be so fast.

E420s using another hard drive is Seagate 7200 rpm 320GB hard drive, the specific model is ST320LT000, 7mm thin part of a single platter drive, read and write typical line is relatively smooth.

With powerful graphics card and the power of the second generation of i5 processors, E420s test in 3D Mark 06 score of 7146 achieved, with this result, E420s enough to cope with the vast majority of 3D games needs.

Generally speaking, Lenovo ThinkPad Edge E420s battery vary significantly not only in appearance by adding a number of elements of fashion and trends, even many advanced technologies used in the body of this high-end business. Something inherent in many ThinkPad E420s who has been in a good heritage, whether it is quality, performance and core technology. It should be said, this is a successful innovation. Combined with 3D in the upcoming blockbuster “Transformers 3″ will appear ThinkPad Edge historic elite version of the figure, let us look forward to ThinkPad Edge Elite version in the film to have excellent performance at the same time, more expect it to have a more astonishing market performance.

Dell Vostro 3300 Notebook/Laptop Review

Posted at January 29, 2012

The Dell Vostro 3300 is a 13.3-inch screen entry level business laptop that comes with the latest Intel Core i3 and i5 of processors and features a thin and light design. The Vostro 3000 series the 3300 belongs to is replacing the old Vostro 1000 series. The new Vostro 3000 series features an updated design and performance improvements. While the Vostro 3300 is marketed under the Dell Business laptop brand, it can serve very well as a student laptop or home laptop since the price is very competitive and has the performance and features desirable to anyone looking for a portable computer to get work done.

Though this is a low priced configuration, you’re able to configure a lot of cool options on the Vostro 3400 that would be more expensive. You can add a backlit keyboard, fingerprint reader, faster Core i5 processor, Nvidia 310m graphics, up to 8GB of RAM, and integrated WWAN wireless. Once you start adding a lot of the higher end features the price can quickly go above $1,000 so you need to pick options that make sense for your needs.

Dell Vostro 3300 Design

The Dell Vostro 3300 design is a definite improvement over the Vostro 1320 we reviewed and that this is replacing. I did not like the glossy finish of the Vostro 1320, the Vostro 3300 instead uses a matte finish and with the Aberdeen Silver color lid I have it looks like an aluminum finish on top. You can also get an attractive Lucerne Red or Brisbane Bronze color finish. The Vostro 3300 is also overall thinner and lighter than the Vostro 1320, which is a big plus.

At the top of the keyboard are touch sensitive media buttons that light up when touched, which is a cool and attractive look. There are also indicator lights on the top row to show things like wireless and hard drive status.

While the keyboard area is all black, the lid color carries over to the left and right sides of the laptop, making for a more uniform and colorful look. I really like the fact that the new line of Vostros aren’t totally black like the last generation.

One thing I don’t like about the design is the fact the frame around the screen is so wide. This is no MacBook Pro like design where the glass screen goes right to the edges or the HP “Infinity View” look which are definitely attractive.

Dell Vostro 3300 Build Quality

The Vostro 3300 has an aluminum case, not plastic, so it looks great and feels quite sturdy. The aluminum is definitely not as thick as you get in other laptops such as the MacBook Pro, so there is a slight amount of flex on the lid and keyboard area. The flex is nothing to be greatly concerned about though, I only noticed this flex when I firmly pushed on the lid and keyboard. During typing I did not notice any flex. The great benefit to aluminum over plastic is that it won’t crack when dropped. The hinges for the screen are very sturdy feeling, there was no wobble to the screen whatsoever and the screen was held firmly in place no matter what angle you place it.

Many people are concerned with the weight of a laptop if they need it for mobile needs. With a 4-cell battery and the optical drive in the Vostro 3300 weighs in at 4lbs and 4.4 ounces, which is 4.275 pounds and almost exactly what Dell’s quoted weight of 4.28lbs is. Overall that’s pretty light weight that will definitely not give you back ache when in a back pack and is very easy to carry with just one hand.

Dell also included a hard drive free-fall sensor so that in the case of drops the hard drive head is parked to prevent data loss. The keyboard has spill proof protection so that during a liquid spill onto the keyboard the liquid is carried away from sensitive internal components.

Overall I think the build quality of the Vostro 3300 is good, it’s not as great or rugged feeling as the Dell Latitude business series but for the price you pay it is impressive.

Dell Vostro 3300 Performance

As I stated at the beginning, the configuration I got for the Vostro 3300 is a budget one as I do not need amazing performance or much power to do my everyday work. I got the slowest Core i3 processor available and the integrated Intel graphics. You can get up to a Core i5 2.4GHz processor, Nvidia 310m graphics and 6GB of RAM in the Vostro 3300 if you’re looking for more horse power.

Frankly speaking, the Core i3 processor and integrated graphics will be enough for many mobile small business users or students that are just looking to use productivity applications such as Microsoft Office and using the web to get work done. If you’re into gaming, multimedia production and design or tons of multi-tasking then you can certainly benefit from a more powerful configuration. Using the Core i3 and just 2GB of RAM I was satisfied with the performance of the Vostro 3300 for everyday tasks. In addition, HD Video playback using online sites such as Hulu.com or YouTube.com was smooth and flawless thanks to the processing power. While the Core i3 isn’t close to being the most powerful new Intel processor, I think it offers plenty enough power for mainstream users.

The bootup time for the Vostro 3300 takes around 45 seconds. There wasn’t much bloatware on board the Vostro 3300 so that definitely helped bootup time along with the fact the hard drive is a speedy 7200RPM.

Below are some benchmark scores for the Vostro 3300. When comparing the Vostro 3300 to other similar sized laptops you can see that the Core i3 processor helps to boost performance over older laptops with Pentium and Core 2 Duo processors.

Dell Vostro 3300 Screen

The screen on the Vostro 3300 is 13.3″ diagonally in size and has a standard 1366 x 768 widescreen resolution, there are no higher resolution offerings for the Vostro 3300. Many will be happy to know the screen is not glossy but instead matte and anti-glare. This is great for working in an office environment since you won’t get any annoying reflections off of the screen. The downside to a matte screen is that colors do not pop as much, but if you’re just trying to get work done that’s no matter.

The actual brightness of the screen is good, it’s as bright as you’ll need inside but of course not bright enough for outdoor viewing (for that you need a specially equipped laptop with a high brightness screen). The viewing angles are not so great, colors change quite a bit if you do not view the screen straight on at a nearly perpendicular angle – which most users do so it’s not a problem.

Dell Vostro 3300 Battery Life

The Vostro 3300 comes standard with a 4-cell dell Vostro 3300 Battery that fits flush with the body of the laptop. You can get a higher capacity 8-cell battery that juts out the back, but currently those are on back order so you have to order it separately from the Vostro 3300 as an upgrade accessory. Using the 4-cell DELL Vostro 3350 battery I was able to get exactly 3 hours and 34 minutes with screen brightness set to the third level, wireless on and the laptop idling. Under more realistic usage conditions in which I actually used the laptop to do web browsing and typing documents I got between 2.5 – 3 hours. Compared to other laptops I’ve used recently these battery life numbers are quite poor. If you need long battery life I’d recommend going for the 8-cell battery or considering a laptop that uses an Intel low voltage processor, such as the Vostro V13 maybe, in which the emphasis is battery life over performance.

The power adapter on the Vostro 3300 is quite small, it only added about 12 ounces of weight when carried with the laptop so that’s a bonus.

Dell Vostro 3300 keyboard and touchpad

The keyboard on the Vostro 3300 is full sized and comfortable to use and type on. An added bonus is that it’s spill proof. I mentioned before that there is a bit of flex in the keyboard, especially towards the center, but during actual typing I didn’t notice the flex – you have to physically push down to create any bending of the keyboard. The key travel is solid and fairly short, which allows for fast typing.

I really like the touchpad on the Vostro 3300. I’ve come across so many bad touchpads over the past few months that it was a relief to use one that felt good and simply worked. I think it’s great that the touchpad is recessed so you can easily feel it and slide your finger around. The mouse buttons are fantastic, they’re just the right size and have a nice and soft travel providing just the right amount of feedback to indicate you have clicked. The touchpad supports gestures such as zooming and also offers vertical and horizontal scroll areas.

Dell Vostro 3300 Port Selection

The Vostro 3300 has a pretty standard selection of ports for a business laptop. I was a little disappointed there was no HDMI port for video and audio output, but that’s still considered a port more geared towards consumers so not surprising it is omitted for the Vostro 3300. What you do get in terms of ports are the following: Ethernet LAN, USB 2.0 (2), USB 2.0/eSATA combo (1), Microphone jack, Headphone/speaker out, 5-in-1 card reader, 34 mm ExpressCard, 15-pin VGA video connector. To see where each port is on the laptop let’s take a tour of the sides:

Left side: Power jack, USB port, Ethernet port, optical drive, 34mm ExpressCard expansion slot

P1020827

Front side: 5-in-1 media card reader, microphone and headphone jack, wireless on/off switch

P1020830

Right side: USB port, USB/eSata port, monitor out port

P1020832

Dell Vostro 3300 Audio

The Vostro 3300 only has one speaker on the front side of the laptop, and it’s a small speaker at that. The speaker quality is quite poor, music is definitely not given any justice. A pair of decent headphones to plug-in will definitely be needed if you want good audio quality when watching a movie or listening to your favorite tunes.

Dell Vostro 3300 Heat and Noise

The Vostro 3300 configuration I had gave no issues with overheating or constant fan noise. The only time the fan (located on the right back side) got loud and revved into high speed was during the running of a benchmarking program, which is to be expected. In general the fan was running at a low speed and very quiet. There was some heat buildup on the right palm rest, but nothing I would call exceptional and never was it bothersome to me.

Conclusion

Overall I come away being impressed with the Dell Vostro 3300 as it offers a lot of bang for the buck. For under $700 I got a high quality built laptop with good performance and a light weight. The poor battery life is a bummer for sure, if you need more than four hours on battery you’ll have to get the larger 8-cell battery which will add weight and cost. The fact you get a new Core i3 or i5 processor, optical drive built-in, weight of around 4 lbs, aluminum case, appealing design and very mobile form factor all for $700 – $1,000 depending on the configuration I would consider the Vostro 3300 a strong buy for students and business workers that are interested in this laptop.

Dell Latitude E5520 2nd Generation Intel Core Notebook Review

Posted at December 14, 2011

One of the first notebooks to pass through our Test Centre using Intel’s 2nd Generation Core i5 CPU is Dell’s Latitude E5520. It will be available to Australian buyers from the middle of March and businesses looking for fast notebooks to deploy to their workers should definitely take heed. Not only can the Latitude E5520 tackle run-of-the-mill office and Web tasks with obscene ease, its 2nd Gen Core i5 CPU (codenamed Sandy Bridge) will also complete complex multimedia tasks in a much swifter fashion than its predecessor.

Latitude E5520: Specifications and performance

Our Latitude E5520 shipped with an Intel Core i5-2540M CPU, which is a dual-core CPU that has a 2.6GHz frequency, Hyper-Threading, (for a total of four threads), and Turbo Boost. Compared to the previous generation of Intel Core i5 CPUs, the 2nd Generation Core i5 provides a significant boost in performance for advanced tasks such as media encoding and decoding, and even 3D gaming — even business users need to take some time out. The rest of the notebook’s configuration is comprised of 4GB of DDR3 SDRAM, integrated Intel HD graphics, and a 500GB, 7200rpm hard drive.

The CPU has a Turbo Boost frequency that can hit a maximum of 3.3GHz. This is well above the standard 2.6GHz clock speed of the CPU, and it’s of most benefit when performing tasks such as creating MP3 files and converting video files from one format to another (transcoding). In our tests, the CPU ran at a consistent 3GHz when it was under an 80 per cent load, and under lower loads (under 50 per cent) it was able to reach up to 3.2GHz.

The high speed translated into great performance in our tests. In the Blender 3D rendering test, the Latitude E5520 notched up a time of 40sec, and in our iTunes MP3 encoding test it recorded 48sec. This type of performance is first generation Core i7 territory (the Dell XPS L501x recorded a time of 43sec in the Blender 3D test using eight threads), and it’s a good deal faster than comparable first generation Core i5 laptops we’ve seen, such as the Acer Aspire 5742G. Its time of 51min in our media transcoding test, where we convert a DVD file into a 1.5GB Xvid file using AutoGordianKnot, is one of the fastest times we have seen to date and is a whopping 17min faster than the Acer notebook.

Storage space in the Latitude E5520 is 500GB. Our test unit came with a 7200rpm hard drive (a solid state drive is an option), which recorded a zippy transfer speed of 32.12 megabyte per second in our tests. If you want to sacrifice some capacity for data security, then a 320GB encrypted hard drive option is also available. A freefall sensor is built in to motherboard.

Latitude E5520: Graphics performance

It is perhaps in the 3D processing arena where the biggest gains in performance can be seen compared to the integrated graphics of the first generation Core CPUs. The Intel HD 3000 graphics in the second generation platform provide more than double the performance of the first generation. This was shown in 3DMark06, where the Latitude E5520 recorded a mark of 4255. A typical notebook equipped with a first generation Core CPU with Intel HD graphics can achieve around 1800 in this benchmark. Not only does the integrated graphics processing do a good job on 3D applications, it has a media processing feature that can be used to hardware-accelerate the encoding and decoding of video files.

Latitude E5520: Design, build quality and connectivity

The Latitude E5520 doesn’t look like much when you lift the lid — it’s definitely no Macbook Pro. Its dull black palm rest and bezel are clear indicators that this notebook is meant for business, and it has a style that definitely won’t cause anyone to ooh and aah over it. This isn’t a bad thing, and in fact we don’t think it looks bad at all; it’s nice and neutral. The only somewhat elegant parts of the notebook are its backlit keyboard and its lid, which has a subtle brushed metal look to it and, of course, the chrome Dell logo.

We like the Latitude’s matte screen, which doesn’t suffer from reflections and is therefore perfect for use in bright office environments. The model we reviewed has a 1920×1080-resolution screen, which is very useful when multitasking and using Windows 7′s Aero Snap feature to get windows side by side. Its colour reproduction and brightness were very good during our tests, and we found it comfortable to stare at this screen for long periods of time.

Around the edges of the Latitude, you will find a mixture of old and new connectivity, and also consumer-minded technology. You get USB 2.0 (four of them), eSATA (shared with one of the USB 2.0 ports), Gigabit Ethernet, FireWire, VGA, a 56Kbps modem, a combination microphone and headphone port, an SD card slot, a SmartCard slot, a DVD burner and an HDMI port. The inclusion of HDMI over DisplayPort is an interesting choice, and it panders more to mainstream users rather than graphics professionals. You also get Bluetooth, 802.11n dual-band Wi-Fi, a 2-megapixel webcam, and there is an option for integrated mobile broadband.

The build quality of the Latitude E5520 is very solid. It doesn’t creak when you hold it from the edges and its lid isn’t easy to flex. It has a spill resistant keyboard, a scratch resistant underside and metal plated hinges. Furthermore, a rubber lining around the lid forms a seal to protect the screen from dust and other particles when the lid is closed and latched. At 2.9kg, the Latitude E5520 is comparably heavy for a 15.6in laptop, so it can be a chore to lug it to and from work.

Dell Latitude E5520 Battery life

Our test Latitude E5520 shipped with a large 9-cell dell Latitude E5420 Battery that supplied us with a long life away from an outlet. In our rundown test, in which we disable power management, maximise screen brightness, enable Wi-Fi and loop an Xvid-encoded video, the notebook lasted 4hr 25min. You can get even more life away from an outlet if you substitute the DVD burner for a second dell Latitude E6520 Battery. This makes the Latitude E5520 desirable for field operations or basically any type of job where a power outlet isn’t handy for long periods of time.

Conclusion

Basically, what you’re getting in the Latitude E5520 is a laptop that is super-quick and useful for just about any productivity endeavour imaginable in an office environment. It possesses a good array of old and new connectivity, it has a backlit keyboard and a great Full HD screen, and we think that any businesses that deploy it will get many years of use of it.

Dell Vostro 3550 Notebook Review

Posted at December 14, 2011

The Dell Vostro 3550 is a 15.6in, 2.7kg business notebook with a swag of great features. The standout of these features is Intel’s 2nd Generation Core i7 CPU, which gives the Vostro 3550 plenty of speed and, in conjunction with a 9-cell dell Vostro 3550 Battery, a very long life away from a power outlet. It’s also blessed with a comfortable backlit keyboard, USB 3.0 ports and a massive touchpad.

Specifications and performance
Indeed, there’s a lot to like about the Vostro 3550, and it all starts under the hood. The 2nd generation Intel Core i7-2620M CPU runs at 2.7GHz and has two cores and Hyper-Threading, along with a Turbo Boost speed of 3.4GHz. It also features integrated Intel HD Graphics 3000, which are powerful enough for a business user in their own right, but Dell has nevertheless included a separate AMD Radeon HD 6630M graphics adapter, which offers even more grunt. The rest of the configuration is made up of 4GB of DDR3 SDRAM and a 500GB, 7200rpm hard drive.

The Vostro performed well in our Blender 3D rendering and iTunes MP3 encoding tests, recording times of 37sec and 44sec in these tests, respectively. Additionally, it recorded a time of only 51min in our video transcoding test, where we convert a DVD file into a 1.5GB Xvid file. All of these results are among the fastest we’ve seen from a notebook to date and it just goes to show how much power the little Sandy Bridge CPU possesses. Not only that, it runs very cool; you can use the Vostro on your lap for prolonged periods of time without feeling the heat unless you are performing tasks that make the hard drive and AMD graphics adapter work hard.

See how the Vostro compares to other Sandy Bridge notebooks we have seen: MSI CR640, Dell Latitude E5520, Sony VAIO SB Series, Sony VAIO CB Series

In 3DMark06, the integrated Sandy Bridge graphics recorded a very good mark of 4389. This is more than enough grunt for everyday office applications and also for editing photos and some gaming. Switching to the AMD Radeon HD 6630M adapter bumped the 3DMark06 score up to 7510, which means you definitely can use the Vostro 3550 to play games in your downtime. The system automatically selects which graphics adapter to use depending on the application, but you can also customise the graphics profile to allow applications to run with your preferred adapter. If an application doesn’t have an adapter assigned to it already, a pop-up is displayed so that you can select the appropriate adapter.

Vostro 3550 Battery life
Using the default Sandy Bridge graphics, our DELL Vostro 3450 battery rundown test lasted 5hr 5min. This is as long as we’ve seen a 15.6in notebook last in our rundown test, in which we disable power management, enable Wi-Fi, maximise screen brightness and loop an Xvid-encoded video; it’s longer than the time recorded by the MSI CR640 notebook that we recently reviewed, and this is due to the larger DELL Vostro 3550N battery in the Vostro. The 9-cell DELL Vostro 3750 battery sticks out of the back of the unit, not only giving the notebook a long life away from an outlet, but also a convenient gripping point for carrying the notebook. You will be able to get more than 5hr 5min of battery life if you just use it for basic tasks and also employ a power management strategy and lower the screen brightness.

Design and features
Physically, the Vostro 5530 is a delight in minimalist design. It’s not overloaded with ports and shortcut buttons, and the only piece of flair comes from the chrome trim around the large touchpad and the keyboard. The chassis feels solid, and the screen is held in place by strong hinges. We love the touchpad, which is 100x57mm and has soft buttons. The keyboard, too, has soft buttons that don’t require too much effort to press and they have a rounded design that feels comfortable and looks good. The keys look even better when they are lit up! You can enable the keyboard’s backlight by pressing the Fn-F6 key combination, and you can select from two brightness levels.

There are three one-touch shortcut keys above the keyboard: one brings up the Windows Mobility Centre, through which you can change most of the laptop’s settings (including the keyboard light); another key brings up the Dell Support Centre, through which you can update drivers and back up data; and the final key is the Dell Instant Launch Manager, which lets you assign your own application.

The screen is a standard 1366×768-resolution, 15.6in panel. It has a matte finish so you don’t have to worry about reflections while you use the laptop in a bright area. Its brightness and contrast are adequate, but its vertical viewing angles, like most laptop screens, are narrow.

Around the edges, the Vostro 5530 has a lot of useful features: a DVD burner, an ExpressCard/34 slot, an SD card slot, microphone and headphone ports, four USB ports (one of which doubles as an eSATA port and two which support USB 3.0), Gigabit Ethernet, VGA, and HDMI. You also get a webcam, Bluetooth and 802.11n Wi-Fi. A fingerprint reader is located on the palmrest, just under the right side of the keyboard, and it can be used to log in to the system and also to serve as a substitute for typing in a password when accessing your favourite Web sites (passwords can be stored in the DigitalPersona Fingerprint software).

Our review unit also came with a built-in, unlocked 3G module, but Dell informed us that this won’t be offered right away for the Vostro 3550, but that it may be included at a later date.

Conclusion
It’s hard not to like the Vostro 3550; it looks good and feels comfortable to use. We like its backlit keyboard and huge touchpad, and it has a useful array of ports along its edges. Best of all, it has fast performance and long battery life thanks to the Sandy Bridge Core i7 CPU and 9-cell battery.

Dell Inspiron 15R N5110 laptop Review

Posted at December 13, 2011

There’s nothing better than an cheap laptop that glances fashionable and performs well, and with the Dell Inspiron 15R N5110, that’s precisely what you get. It’s a sub-$600 notebook that’s based onto Intel’s 2nd Generation Core i3 CPU, it’s comfortable towards consume for the most portion, and it also lets you towards customise its lid design so that your notebook can stand out and glance special.

Specifications and performance
Our pre-production Inspiron 15R arrived with a form that you won’t be able towards buy (2GB of RAM and a 320GB steely momentum instead of 4GB of RAM and a 500GB steely drive), but it still served well within our tests. In the Blender 3D rendering and iTunes MP3 encoding challenges, the notebook’s 2.1GHz Intel Core i3-2310M CPU registered moments of 57sec and 1min 8ec, respectively.

To put this operation within perspective, it’s approximately as fast as a 2.53GHz former generation Core i3 CPU. For example, the Medion Akoya E7216, which arrived with a 2.53GHz Intel Core i3-380M CPU registered 59sec within Blender and 1min 2sec within iTunes. The Medion also took 1hr 10min towards convert a DVD file into a 1.5GB Xvid file, whereas the Inspiron 15R took 1hr 15min. So you can see that despite having a slower frequency, the Dell’s CPU can still hold its own and it processes you can consume the 15R towards convert videos for your telephone and also for photograph and TV editing tasks.

The R N5110 earns consume of the integrated graphics within Intel’s Sandy Bridge CPU, and this graphics solution registered 3316 marks within 3DMark06. It’s a respectable outcome for such a cheap laptop and it processes that you can consume it towards play a number of toys during you consume a low conclusion and low graphics item settings.

Features and construct quality
The connectivity choices round the edges of the 15R N5110 are very useful; you get modcons such as HDMI, eSATA, and USB 3.0 (two of them), as well as stalwarts such as 10/100 Ethernet, VGA, USB 2.0, an SD card slot, and headphone and mike ports. You also get a built-in DVD burner, a webcam, 802.11n Wi-Fi (up towards 150Mbps) and Bluetooth. Basically, it’s a well-stocked machine for the price you’re paying.

We want the glance of the Inspiron 15R. It has a nice rounded design, and the chrome round the keyboard is elegant. We relish the unit’s status lights, which are a nice white colour instead of a retina-burning, super-bright blue. The screen is glossy and it suffers from reflections, as well as destitute vertical regarding angles; the glossy bezel can be distracting, too. On the else side of the screen, the lid can be swapped so that you can consume a different design — it merely slips off. We’re a bit wary of this design although, as the lid envelopes arrive off a bit too easily (a latch is show towards hold them within site, but it didn’t seem towards profession properly onto our experiment model). You possess towards be careful when bringing the notebook, just within instance you hold it the inaccurate distance and the lid slips off and you descent the laptop!

The overall construct quality of the Inspiron 15R N5110 is decent. It feels well scaled and not too heavy (it weighs round 2.6kg), but the deserted side is creaky. The chassis earns clicking noises as you put pressure onto the palmrest, and the deserted side of the keyboard is also a little too bouncy and noisy when you beaten the keys. The keys are gentle and possess nice drift although, so it’s not uncomfortable towards model onto this notebook for long periods of time. It shall get a little warm as you consume it onto your lap for long periods of moment although — specially whether you are operating applications that require lots of processing.

The touchpad is huge (102x56mm) and embraces plenty of single- and dual-finger gestures, and it has beautifully gentle buttons. You can customise the wave cooperation towards your liking across its driver program.

dell Inspiron N5110 Battery life
A 48Wh (Watt-hour) Inspiron N5110 Battery sits snugly within the spine of the chassis. In our dell Inspiron 15R Battery rundown experiment, within which we disable power management, enable Wi-Fi, maximise screen brightness and loop an Xvid-encoded TV, the Inspiron 15R lasted 3hr 33min. This is a nice outcome for a cheap 15.6in laptop, but it’s 17min off what the Core i5-equipped MSI CR640 achieved within the equivalent test.

Conclusion
What you get within the Dell Inspiron 15R N5110 is a cheap notebook with lots of nice features, respectable hurry, and nice battery life. You also get a creaky chassis and an overly glossy screen with narrow regarding angles, and an proficiency towards customise the distance the laptop glances via installing a lid with a funky paint job. Overall, despite there being a few negatives within its construct quality, the Inspiron R is a nice notebook.

Evaluation Engineer Comments:

Is well known ,12-14-inch notebook is still the mainstream of today’s notebook market. 12 inches more attention to the portable notebook, but the relatively low performance does not meet some of the needs of the user, the consumer can only spend money in exchange for a more robust high-priced configuration. 14-inch notebook will have a good performance, but their portability is greatly reduced, the volume is too large often cause trouble for the user to carry. 13-inch notebook are a good balance between these two points, a reasonable configuration has good portability. Recently, Toshiba officially announced a 13.3-inch notebook – Toshiba Portege M830, it has beautiful sounds of nature A black face, fashion, and yet calm. Were equipped with Intel Pentium Dual Core T3400 processor and Intel GMA X4500 integrated graphics can what kind of surprise?This 13.3 inches Xiaobian will give you detailed models.

Toshiba Portege M830 M802 after another, following a consumer notebook, the continued use of the 13.3-inch screen, look past the abandoned Toshiba Satellite M Series models with black and silver, while the whole body turned to the popular black piano paint.

Toshiba Portege M830 A-side and different than before, eliminating the need for pre-built gray lines, sounds of nature instead of a simple black-based colors, which also cater to people now aspire to the simple life. LOGO is very eye-catching white middle, and the A side of black to form a good match. Toshiba Portege M830 described above with a black piano, so prone to the use of fingerprints and scratches, the user routine maintenance costs will be more than a lot of thought to.

Open the screen cover, the Toshiba Portege M830 fancy platform appeared. Overall, M830 did not follow the operating platform for the appearance of body style, interior and overall use of high-gloss paint with Obscure, highlight the airplane’s technology lifestyle.According to Toshiba, the official introduction, M830 platform Obscure and not only play a simple modification, which consists of aluminum materials from repression, can be shielded from the radiation inside the body, but also further improve the overall body of the shock degree.

Second, the Toshiba Portege M830 operational description

As a 13.3-inch notebook, with good portability is important, but essential for good maneuverability. Toshiba Portege M830 with a matte surface of the keyboard, it can provide very strong fingers and friction between the keyboard and reduce the emergence of a finger sliding due to the emergence of input errors. I also personally feel a bit, there is a smaller keyboard in the operating noise, and the keys feel more rigid, new users may have to take some time to adapt.

Toshiba Portege M830 Keypad at a Glance

Notebook touchpad has great features, the overall embodied in the head. However, to improve the whole appearance, but also a corresponding reduction in the notebook operational. The touch pad and control platform to form part of a unified visual effects, also has a striped appearance, but striped with a matte surface. Toshiba Portege M830 in hand on the side of the touchpad astringent, and because too much mixed with the platform, often occur in the operation of border phenomena. Left and right mouse buttons as a whole more rigid, and a sleek design allows the operator to feel uncomfortable, and right mouse buttons are also easy to leave fingerprints.

Third, the Toshiba Portege M830 interface layout description

Toshiba Portege M830′s interfaces will bring us what kind of surprise? The left side of the fuselage has a laptop VGA port, 2 USB2.0, IEEE1394, HDMI interface and EX card interface. It should be noted that the Toshiba Portege M830′s USB port and HDMI too close, there are some similarities in appearance, it is easy to mislead the user an error in the course of operation. Overall, the interface left quite satisfactory, the overall feel is more abundant, especially with the IEEE1394 interface and HDMI interfaces.

About the notebook interface section

Toshiba Portege M830 is the right side of the fuselage were many low-key, where the design of a double burner, USB interface, cable interfaces, and computer keyhole. In addition, the Toshiba Portege M830 in front of the fuselage provides the user with multi-card reader, wireless LAN hardware switch and volume control dial. Although the sound control dial design is very simple, but it has a strong operational, design bold enough, there are features.

Notebook in front of the interface part of the

As the Toshiba Portege M830 does not use a sunken shaft, so there is enough space for the rear of notebook design more interfaces. As the power cord plug is rarely in use, so the Toshiba Portege M830 power interface design in this, can give users a good clean operating environment.

Equipped with a 1.3 megapixel camera

Toshiba Portege M830 LCD screen frame built 1.3 million pixel camera, and now this is nowadays a standard laptop configuration, provide users with more channels of communication. We can see Toshiba Portege M830 camera with a fixed design, so popular rotating relative to the current design is somewhat fly in the ointment.

Configuration, the Toshiba Portege M830 uses a 45nm manufacturing process Intel Pentium Dual Core T3400 processor, clocked at its 2.16GHz, 667MHz front side bus, 1GB of RAM nowadays regarded as the mainstream configuration. But with software configuration requirements for increasingly high, 1GB of RAM will not meet user’s needs, Toshiba Portege M830, a memory slot reserved for users with plenty of memory upgrades.160GB hard drive and DVD burner, equipped with multiple password encryption, three-dimensional hard disk protection technology, pre-installed Windows Vista Home Basic operating system, fully meet the needs of everyday use.

Weight for 13-inch notebook is particularly important, the Toshiba Portege M830 machine weighs (with toshiba Portege M803 battery) 2017g, travel weight 2488.5g, PA3634U-1BRS battery weight of 308g, for a 13.3-inch notebook, but also the weight and thickness control considered ideal.

Summary:

As a 13.3-inch notebook, stylish Toshiba Portege M830 is the most important feature is very suitable for young users now, and has good portability. Its performance in general, to meet the user’s daily use, but the relatively low performance of integrated graphics can not be good for gamers to create the operating environment. 5K overall and integrated laptop price, Toshiba Portege M830 is a recommended 13.3-inch consumer notebook.
